I always thought it was a mistake to remove record puns in H98. I would not be against re-introducing them into GHC, since they appear to remain in Hugs and are in Yhc.
what you (and all) think about wildcarded puns: data Command = Command { cmd_name :: !String , cmd_arcspec :: String , cmd_arclist :: [FilePath] , cmd_arcname :: FilePath , cmd_arc_filter :: !(FileInfo -> Bool) , cmd_filespecs :: ![String] , cmd_added_arcnames :: !(IO [FilePath]) , cmd_diskfiles :: !(IO [FileInfo]) , cmd_subcommand :: !Bool .... } process_cmd (Command{*}) = do print cmd_name ... because Haskell encourage using of structure name as part of field's name, this will not create mess (at least for my programs), it will work like Pascal's 'with' operator -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
